Merge bitcoin/bitcoin#30307: fuzz: Fix wallet_bdb_parser 32-bit unhandled fseek error
fa7bc9bbca9348cf31b97bee0789ea7caeec635c fuzz: Fix wallet_bdb_parser 32-bit unhandled fseek error (MarcoFalke)
Pull request description:
`std::fseek` on 64-bit past the end of the file may work fine (the following read would fail). However, on 32-bit it may fail early.
Fix it, by ignoring the error, treating it similar to a read error.
This was found by OSS-Fuzz.
